Hmm, well, there was no amplification in any of the NTC or RT- controls; the positive ones are the other curves shown.
I'm looking specifically at the differences in slope/shape at the beginning of the curves. Eg, the positives in the first and third pictures have a small shoulder before the peak, but not the negatives. Wouldn't the exact same product melt exactly the same way? Or is the difference so small that it doesn't matter?
Thanks again in advance
